Model Exponential Growth Question :A sample of bacteria is growing at a continuously compounding rate. The sample triples in 10

Iteru [2.4K]

Answer:

The number of bacteria $B$ after $d$ days is given by

$B = B_0 (3)^{\frac{1}{10} d}$

where $B_0$ is the initial number of bacteria.

Step-by-step explanation:

The number of bacteria $B$ in the sample triples every 10 days, this means after the first 10th day, the number of bacteria is

$B = B_0 *3,$

where $B_0$ is the initial number of bacteria in the sample.

After the 2nd 10th days, the number of bacteria is

$B = (B_0 *3)*3$

after the 3rd day,

$B =( B_0 *3*3)*3$

and so on.

Thus, the formula we get for the number of bacteria after the <em>n</em>th 10-days is

$B = B_0 (3)^n$

where $n$ is is the <em>n</em>th 10-days.

Since, $n$ is 10 days, we have

$d =10n$

$n =\dfrac{1}{10}$

Substituting that into $B = B_0 (3)^n$ , we get:

$\boxed{ B = B_0 (3)^{\frac{1}{10} d}}$

Choose the letter of the equation for<br> the graph.

andreev551 [17]

The graphed trigonometric function is the one in option a.

<h3>Which is the equation of the graph?</h3>

The key parts that we can see on the graph are:

The midline is y = 1.

From this we know that the correct option is either a or b.

at x = 0, f(x) = 0.

Now we can evaluate options a and b in x = 0 and see which one is equal to zero.

for a:

y = sin(0 - pi/2) + 1 = sin(-pi/2) + 1 = -1 + 1 = 0

for b:

y = cos(0 + pi/2) + 1 = 0 + 1 = 1

Then we can see that option a is the correct option.

When you divide a whole number by a decimal less than one, the quotient is greater than the whole number. Why?

Think about it logically. If you have 1 candy bar, how many half candy bars can make up one candy bar.

1 Candy bar/.5 candy bar = 2

2 half candy bars = 1 candy bar.

how many times can .5 fit into 1. 2 times.
